(Halifax, N.S. : Saint Mary's University, 2019)To survive, fish must maintain ionoregulatory and osmoregulatory homeostasis during changes in environmental salinity. In hypersaline water, fish must actively excrete salts and drink water to counterbalance the passive ...
-
(Halifax, N.S. : Saint Mary's University, 2018)The ‘White’ Threespine Stickleback is a form of stickleback endemic to Nova Scotia, Canada, which exists sympatrically with the ‘common’ marine Threespine Stickleback. These fish differ in both morphology and behaviour. ...
-
(Halifax, N.S. : Saint Mary's University, 2023-05-01)Interspecific hybridization occurs when two species successfully mate to produce offspring. This phenomenon is relatively common in nature and can produce hybrids with advantaged, disadvantaged, or intermediate physiology ...
-
(Halifax, N.S. : Saint Mary's University, 2019)Little is known about how salinity tolerance evolves in fishes. In this study I measured salinity tolerance, and candidate mechanisms underlying tolerance, in Common Killifish (Fundulus heteroclitus), Banded Killifish ...
-
(Halifax, N.S. : Saint Mary's University, 2021)Freshwater tolerance has evolved repeatedly in fishes, including in the Gasterosteidae family. However, Blackspotted Stickleback (Gasterosteus wheatlandi) and the endemic Nova Scotian “white” Threespine ...
-
(Halifax, N.S. : Saint Mary's University, 2020)Fishes have evolved freshwater tolerance multiple times, using different physiological mechanisms, and we have much to learn about how fish can adapt to freshwater. Sticklebacks in the family Gasterosteidae are becoming ...
-
(Halifax, N.S. : Saint Mary's University, 2020)Often the most striking displays of colour in animals arise from interactions during mating. Nuptial colouration is exclusively associated with mating and typically functions in either female mate choice by signalling male ...
-
(Halifax, N.S. : Saint Mary's University, 2018)The white Threespine Stickleback (Gasterosteus aculeatus) is an ecotype endemic to brackish environments in mainland Nova Scotia and the Bras d’Or Lake. During the breeding season, ‘white’ males are bright white and provide ...
-
(2021)Hybridization events provide opportunities to examine the mechanisms influencing interspecific reproductive isolation. In Porter’s Lake, Nova Scotia, hybridization between two killifish species (Fundulus heteroclitus ...
-
(Halifax, N.S. : Saint Mary's University, 2021)Fish normally live in salinities ranging from 0 ppt (freshwater) to ~35 ppt (seawater) but most fish can only inhabit fresh or saltwater making salinity a main factor in determining their distribution. While euryhaline ...
-
(Halifax, N.S. : Saint Mary's University, 2019)The majority of vertebrates reproduce sexually, but a small percentage can reproduce clonally (asexual reproduction). The Common killifish (Fundulus heteroclitus) and Banded killifish (Fundulus diaphanus) are found along ...
